Derek Adam Seehausen, a 26-year-old medical student at the University of Southern California, was last seen in Los Angeles on August 5, 2014. He was seen walking on Alvarado Street around midnight after withdrawing $200 from an ATM and had bought groceries earlier that evening. His apartment was later found undisturbed with his keys, wallet, and phone left behind.

Derek is described as 6 feet tall, 180 pounds, with brown hair and hazel eyes. He was wearing a maroon shirt, tan shorts, and bright-colored sneakers when last seen. There were a few unconfirmed sightings in the weeks after his disappearance, including reports of him on a Metro bus and along the Pacific Coast Highway, but none led to a confirmed location.

Derek’s family says he was punctual and committed to his anesthesiology studies and had no history of mental illness or personal issues. If anyone saw Derek around Alvarado Street or on public transit the night of August 5, 2014, or has information about those unconfirmed sightings, please come forward.
